[0001] DEVICE AND METHOD FOR DISCHARGING A GAS MIXTURE

[0002] The invention relates to a hypoxia device for conducting hypoxia treatment and / or hypoxia training, comprising a gas reservoir, a gas delivery device, a supply line suitable and intended for conducting a gas mixture from the gas reservoir to the gas delivery device, and / or a discharge line suitable and intended for conducting a gas mixture from the gas delivery device to the gas reservoir.

[0003] State of the art

[0004] Hypoxia can trigger reactions in every cell in the body and enable increased energy metabolism. It can contribute to the activation of a variety of genes. Athletes, as well as healthy and sick individuals, can benefit from hypoxia.

[0005] The effectiveness of altitude training has long been known. However, until a few years ago, there was no adequate explanation for how slight oxygen deficiency leads to improved performance in the body. The observed increase in red blood cells was not enough to explain the changes in the body. The breakthrough in understanding came with the discovery of the hypoxia-inducible factor HIF-1-alpha. This factor provided an explanation for the comprehensive effect of altitude training. The abbreviation HIF stands for Hypoxia-Inducible Factor. The technical term refers to an oxygen sensor that becomes active when there is not enough oxygen in the body's cells. It controls one of the body's most vital processes: the adaptation of cells, tissues, and organs to a lack of oxygen. At the same time, it signals self-repair in the body. The best-known positive effect of HIF is the synthesis of erythropoietin (EPO) in the kidneys and liver.Before the discovery of HIF, it was used to explain changes in the cardiovascular, respiratory, and circulatory systems. It is now clear that the improvement in performance is much more comprehensive. The endothelial cells of the tunica intima respond to the influence of hypoxia with increased nitric oxide (NO) synthesis. This gas decisively influences vascular dilation. It leaves the endothelium and causes relaxation of the smooth muscle cells in the surrounding tissue. At the tunica intima itself, NO prevents platelet adhesion and aggregation. Also interesting in this context is that under the influence of hypoxia, the endothelial cells produce the angiogenic factor VEGF. Its production leads to neoangiogenesis of the capillaries during hypoxia therapy. These additional vessels are very often located in damaged or poorly perfused tissue sections.

[0006] All known pendulum breathing-based devices for hypoxia training contain at least one breathing reservoir into which a specific amount of atmospheric air is introduced at the beginning of each diagnostic, training, or therapy session. As the user, connected to this reservoir, inhales and exhales from it, the oxygen in this reservoir is consumed, creating an oxygen-deficient gas mixture containing oxygen. This mixture is purified of excess carbon dioxide, and the residual oxygen content is measured at least periodically during each session.

[0007] The document WO 2012 / 005712 presents a device for breathing with hypoxic gas mixtures comprising: a support frame; a breathing container with an inspiration valve, a first sensor for the oxygen content and an absorber for CO2 and H2O; a controllable compressor connected to the breathing container via a puff valve; a chamber for the extraction and accumulation of aliquot gas mixtures, equipped with a second sensor for the oxygen content, a controllable adjustment valve and a controllable ejector; a user attachment; an inspiration line with a controllable central valve and a first flow meter for the inspiration rate; a T-piece; a main expiration line equipped with a first air blower and connecting the attachment to the reservoir;Additionally, an expiratory line equipped with a second flowmeter for measuring the volume of sample aliquots and a second air blower, connecting the port to the chamber; additional sensor complex and control unit.

[0008] The device presented here is very complex in design and therefore very expensive to purchase. Its use is particularly complex for a private user and must therefore be carried out under professional supervision.

[0009] It is therefore an object of the present invention to provide a hypoxia device for conducting hypoxia treatment and / or hypoxia training that enables efficient, cost-effective, and safe hypoxia training for a private user, even without professional supervision. It is also an object of the present invention to provide a method for conducting hypoxia training that enables safe and efficient conduct of hypoxia training for a private user, even without professional supervision.

[0010] The stated object is achieved by means of the hypoxia device for carrying out a hypoxia treatment and / or a hypoxia training according to claim 1. Further advantageous embodiments of the invention are set out in the subclaims.

[0011] The device according to the invention for conducting hypoxia treatment and / or hypoxia training comprises a gas reservoir. The gas reservoir is an air or gas reservoir containing the gas mixture for conducting hypoxia treatment and / or hypoxia training. Furthermore, the hypoxia device for conducting hypoxia treatment and / or hypoxia training comprises a gas delivery device. The gas delivery device is typically designed as a breathing mask that a user wears over the breathing openings (mouth and nose) for conducting hypoxia treatment and / or hypoxia training.Furthermore, the hypoxia device for conducting hypoxia treatment and / or hypoxia training comprises a supply line suitable and intended for conducting a gas mixture from the gas reservoir to the gas delivery device, and / or a discharge line suitable and intended for conducting a gas mixture from the gas delivery device to the gas reservoir. The supply line and / or discharge line is typically designed as a flexible hose and connects the gas delivery device to the gas reservoir in a gas-tight manner. Furthermore, the hypoxia device for conducting hypoxia treatment and / or hypoxia training comprises a CO2 sensor arranged in the supply line and / or discharge line.

[0012] The hypoxia device according to the invention is a so-called pendulum breather, meaning the user repeatedly inhales and exhales the same air. Normal breathing air contains 21% oxygen. With each breath, approximately 4% oxygen is removed from the inhaled air and replaced by a corresponding amount of exhaled carbon dioxide (CO2). A given volume of air can therefore, in principle, be "breathed through" several times until its oxygen content is exhausted; however, the exhaled carbon dioxide accumulates in the air in the breathing circuit. Furthermore, there are physiological risks associated with too much carbon dioxide in the inhaled air: A concentration of 5% or more leads to unconsciousness, and 8% or more can lead to death over a longer period of time.

[0013] For this purpose, the hypoxia device according to the invention comprises a CO2 sensor arranged in the supply line or the discharge line of the breathing circuit. The CO2 sensor can preferably continuously measure the CO2 content of the breathing air. The CO2 sensor can, for example, have a visual and / or acoustic indicator and / or be connected to a visual and / or acoustic indicator that emits a warning signal when the CO2 content of the breathing air in the breathing circuit, as detected by the CO2 sensor, reaches a level that is dangerous for the user.

[0014] Furthermore, the hypoxia device according to the invention can comprise a CO2 absorber, which is also arranged in the supply line and / or discharge line. The CO2 absorber is typically a mixture of calcium hydroxide and sodium hydroxide in solid form (so-called soda lime). During hypoxia treatment and / or hypoxia training, the air flows through the soda lime, in which the carbon dioxide is first bound to sodium hydroxide, which is then regenerated by the calcium hydroxide, also known as slaked lime, also contained therein. The CO2 sensor thus also monitors the functionality of the CO2 absorber.

[0015] In an optional embodiment of the invention, the hypoxia device is designed as a closed circuit. Especially in a closed circuit, it is important to monitor the gas conditions, including the CO2.

[0016] In a further development of the invention, the CO2 content of the gas released via the gas release device can be monitored using the CO2 sensor. The CO2 content of the air inhaled and exhaled by a user through the gas release device can preferably be continuously measured.

[0017] In a further embodiment of the invention, the hypoxia device comprises a threshold monitoring unit. The threshold monitoring unit has a threshold value for the CO2 content of the gas released via the gas release device. If the CO2 content determined by the CO2 sensor exceeds the threshold value, a corresponding signal is output and / or the gas release by the gas release device is discontinued.

[0018] In a further embodiment of the invention, the threshold monitoring unit comprises a control unit. The control unit can be controlled by the control unit. For this purpose, the control unit comprises a processor and a suitable app.

[0019] In a further development of the invention, the control unit is connected to a storage unit. The storage unit contains the app for controlling the threshold monitoring unit. In a further embodiment of the invention, a threshold value for the maximum CO2 concentration is stored in the storage unit.

[0020] In an advantageous embodiment of the invention, the CO2 concentration determined by the CO2 sensor can be monitored by the threshold monitoring unit for any exceedance of the CO2 concentration threshold. In particular, the threshold monitoring unit compares the determined CO2 concentration with the threshold for the CO2 concentration. If the determined CO2 concentration exceeds the threshold stored in the storage unit, a visual and / or acoustic warning signal can be output by the threshold monitoring unit, for example, to warn a user of the hypoxia device. Alternatively or additionally, the threshold monitoring unit can interrupt the gas supply to the gas delivery device.

[0021] In a further embodiment of the invention, the hypoxia device has an automatic shutdown device. The shutdown device is preferably also controlled by the control unit of the threshold monitoring unit. The shutdown device is automated in such a way that it is activated without user intervention.

[0022] In a further advantageous embodiment of the invention, the gas supply to the gas delivery device can be interrupted by the shutoff device. If the determined CO2 concentration exceeds the threshold value stored in the storage unit, the shutoff device interrupts the gas supply to the gas delivery device in such a way that a user can no longer perform hypoxia training and must remove the gas delivery device from their breathing openings. In a further embodiment of the invention, the shutoff device has a shutoff valve for this purpose.

[0023] In an advantageous embodiment of the invention, after activation of the shutdown device, CO2 is discharged or removed from the breathing circuit with the aid of an inlet and / or outlet valve. Furthermore, it is possible to introduce air and / or oxygen into the breathing circuit with the aid of the inlet and / or outlet valve. After the gases have been discharged or introduced, the shutdown device is reset. Optionally, the CO2 sensor is coupled to a two-point controller that controls the inlet or outlet valve. When a first threshold is reached, the inlet or outlet valve is opened to introduce air and / or oxygen or to discharge CO2. When the second threshold is reached, the inlet or outlet valve is closed again. The first threshold for the CO2 content is at a higher CO2 concentration than the second threshold. Optionally, a third threshold can be provided that activates the shutdown device.The third threshold for the CO2 concentration is higher than the first and second thresholds.

[0024] In a further advantageous embodiment of the invention, the hypoxia device comprises a CO2 absorber that absorbs the CO2 from the exhaled air. In this embodiment, the CO2 sensor is arranged adjacent to the CO2 absorber to monitor its function. If the CO2 sensor detects a limited function of the CO2 absorber, the shutdown device is activated. In an optional embodiment of the invention, the function of the CO2 absorber is monitored by two CO2 sensors. The first CO2 sensor is arranged upstream of the CO2 absorber, and the second CO2 sensor is arranged downstream of the CO2 absorber. During monitoring, the measured values ​​determined by the CO2 sensors are compared.

[0025] The object is further achieved by means of the method according to the invention for conducting hypoxia training. Further advantageous embodiments of the invention are also set forth in the subclaims.

[0026] The method according to the invention for conducting hypoxia training comprises two steps: In the first step, a hypoxic gas mixture is provided. The hypoxic gas mixture has, in particular, a reduced oxygen content compared to conventional breathing air.

[0027] In the second process step, a measurement signal is acquired using a CO2 sensor. The CO2 sensor preferably continuously measures the CO2 content of the gas mixture and generates a measurement signal, which is evaluated by a suitable control unit connected to the CO2 sensor. In particular, the control unit preferably continuously monitors the CO2 content of the gas mixture.

[0028] In a further development of the invention, the measurement signal is recorded in the gas reservoir, the supply line, and / or the outlet of a hypoxia device. The gas reservoir, supply line, and outlet are connected in such a way that the gas mixture in them has the same composition. Depending on the design and size of the hypoxia device and the spatial conditions of the location of the hypoxia device, a CO2 sensor can be arranged in the gas reservoir, supply line, and / or outlet to generate the measurement signal.

[0029] In an advantageous embodiment of the invention, the CO2 concentration is determined from the measured signal. For this purpose, the CO2 sensor is connected to a control unit that has a processor and a suitable app.

[0030] In a further development of the invention, a threshold value is read from a memory unit. The threshold value determines the maximum CO2 concentration of the respiratory gas at which a user can still perform hypoxia training.

[0031] In an advantageous embodiment of the invention, the threshold value is compared with the determined CO2 concentration. If the determined CO2 concentration exceeds the threshold value stored in the storage unit, the threshold monitoring unit can, for example, issue a visual and / or acoustic warning signal to warn a user of the hypoxia device. Alternatively or additionally, the threshold monitoring unit can interrupt the gas supply to the gas delivery device.

[0032] In a further embodiment of the invention, a shutdown device is activated when the determined CO2 concentration exceeds a threshold value. The shutdown device is preferably also controlled by the control unit of the threshold monitoring unit. The shutdown device is automated in such a way that it is activated without user involvement.

[0033] In a further development of the invention, the activation of the shut-off device interrupts the gas supply to the gas delivery device. If the determined CO2 concentration exceeds the threshold value stored in the storage unit, the shut-off device interrupts the gas supply to the gas delivery device in such a way that a user can no longer perform hypoxia training and must remove the gas delivery device from their breathing openings. In a further development of the invention, the shut-off device has a shut-off valve for this purpose.

[0034] In a further development of the invention, the threshold value is the limit value, whereby the threshold value or limit value refers to the maximum CO2 concentration of the respiratory gas with which a user can still carry out hypoxia training.

[0035] In an advantageous embodiment of the invention, the hypoxia device has an inlet and / or outlet valve. The inlet and / or outlet valve allows CO2 to be discharged or removed from the breathing circuit. Furthermore, the inlet and / or outlet valve allows air and / or oxygen to be introduced into the breathing circuit.

[0036] Optionally, the CO2 sensor can be coupled to a two-point controller with which the inlet or outlet valve can be controlled. When a first threshold is reached, the inlet or outlet valve can be opened to introduce air and / or oxygen or to discharge CO2. When the second threshold is reached, the inlet or outlet valve can be closed again. The first threshold for the CO2 content is at a higher CO2 concentration than the second threshold. Optionally, a third threshold can be provided, upon reaching which the shutdown device can be activated. The third threshold for the CO2 concentration is above the first and second thresholds.

[0037] In a further advantageous embodiment of the invention, the hypoxia device has a CO2 absorber, through which the CO2 from the exhaled air can be absorbed. In this embodiment, the CO2 sensor is arranged adjacent to the CO2 absorber to monitor its function. Should the CO2 sensor detect a limited function of the CO2 absorber, the shutdown device can be activated. In an optional embodiment of the invention, the function of the CO2 absorber can be monitored by two CO2 sensors. The first CO2 sensor is arranged upstream of the CO2 absorber, and the second CO2 sensor is arranged downstream of the CO2 absorber. During monitoring, the measured values ​​determined by the CO2 sensors are compared.

[0046] Fig. 1 shows a view of a hypoxia device 1 for conducting hypoxia treatment and / or hypoxia training. The hypoxia device 1 comprises the gas delivery device 20, which is designed as a breathing mask and is worn by the user P over the breathing openings (mouth and nose) during the hypoxia treatment and / or hypoxia training.

[0047] The hypoxia device 1 also includes the gas reservoir 10. The gas reservoir 10 and the gas delivery device 20 are connected to each other in a gas-tight manner via the flexible gas line 30. During hypoxia treatment and / or hypoxia training, the user P wears the gas delivery device 20 and repeatedly inhales and exhales the gas contained in the gas reservoir 10.

[0048] To monitor the CO2 content of the respiratory gas, the hypoxia device 1 has a CO2 sensor S, which can be arranged at different locations on the hypoxia device 1. The CO2 sensor S can be arranged on the gas line 30 (Fig. 1 a), in the gas reservoir 10 (Fig. 1 b), or in the gas delivery device 20 (Fig. 1 d).

[0049] In another embodiment (Fig. 1c), the gas line 30 can be divided into supply line 40 and discharge line 50. Supply line 40 and discharge line 50 each have a one-way valve V, which allows the circulation of the respiratory gas in the hypoxia device 1 only in one direction. In this embodiment, the CO2 sensor S is arranged in the discharge line 50. However, the CO2 sensor S can also be arranged in the gas reservoir 10 or in the gas delivery device 20.

[0050] Fig. 1 shows a view of a hypoxia device 1 for conducting hypoxia treatment and / or hypoxia training. The hypoxia device 1 comprises the gas delivery device 20, which is designed as a breathing mask and is worn by the user P over the breathing openings (mouth and nose) during the hypoxia treatment and / or hypoxia training.

[0051] The hypoxia device 1 also includes the gas reservoir 10. The gas reservoir 10 and the gas delivery device 20 are connected to each other in a gas-tight manner via the flexible gas line 30. During hypoxia treatment and / or hypoxia training, the user P wears the gas delivery device 20 and repeatedly inhales and exhales the gas contained in the gas reservoir 10.

[0052] To monitor the CO2 content of the respiratory gas, the hypoxia device 1 has a CO2 sensor S, which can be arranged at various locations on the hypoxia device 1. The CO2 sensor S can be arranged on the gas line 30 (Fig. 1 a), in the gas reservoir 10 (Fig. 1 b), or in the gas delivery device 20 (Fig. 1 d). The CO2 sensor S generates a measurement signal with which the CO2 content of the respiratory gas in the hypoxia device 1 can be determined.

[0053] In another embodiment (Fig. 1c), the gas line 30 can be divided into supply line 40 and discharge line 50. Supply line 40 and discharge line 50 each have a one-way valve V, which allows the circulation of the respiratory gas in the hypoxia device 1 only in one direction. In this embodiment, the CO2 sensor S is arranged in the discharge line 50. However, the CO2 sensor S can also be arranged in the gas reservoir 10 or in the gas delivery device 20.

[0054] A variant of the hypoxia device 1 according to the invention is shown in Fig. 2. In this exemplary embodiment, as in the previous exemplary embodiment (see Fig. 1 c), the gas line 30 has a separate supply line 40 and discharge line 50, wherein the supply line 40 and the discharge line 50 also each have a one-way valve V. The CO2 sensor S is arranged in the discharge line 50 and is connected to a control unit C. By means of the control unit C, the CO2 content of the respiratory gas in the hypoxia device 1 can be determined from the measurement signals of the CO2 sensor S. Fig. 3 shows an advantageous exemplary embodiment of the hypoxia device 1 according to the invention. The gas line 30 also has a separate supply line 40 and discharge line 50, each with a one-way valve V. The CO2 sensor S is arranged in the discharge line 50 and is connected to the control unit C. In addition, a shutdown device A is arranged in the supply line 40, which is also connected to the control unit C.The gas supply to the gas delivery device 20 can be interrupted by means of the shut-off device A.

[0055] A preferred embodiment of the hypoxia device 1 according to the invention is shown in Fig. 4. The gas line 30 also has a separate supply line 40 and discharge line 50, each with a one-way valve V. The hypoxia device 1 has the threshold monitoring unit 100, in which the CO2 sensor S, control unit C, shutdown device A, and a storage unit M connected to the control unit C are arranged together. A threshold value for the maximum CO2 concentration of the respiratory gas is stored in the storage unit M.

[0056] To perform hypoxia training, a user P places the gas delivery device 20 over the breathing openings and repeatedly inhales and exhales the same breathing gas. The threshold monitoring unit 100 monitors the CO2 concentration of the breathing gas by the CO2 sensor S detecting a measurement signal of the breathing gas in the line 50 during the hypoxia training. The measurement signal is sent to the control unit C, and the control unit C, using a suitable app, calculates the CO2 concentration of the breathing gas based on the measurement signal received from the CO2 sensor S. The control unit C compares this determined CO2 concentration of the breathing gas with a threshold value stored in the storage unit M, which simultaneously serves as a limit value, for the CO2 concentration of the breathing gas.If the determined CO2 concentration of the respiratory gas exceeds the threshold value, the control unit C sends a control signal to the shut-off device A such that the shut-off device A interrupts the gas supply to the gas delivery device 20. The shut-off device A closes a shut-off valve arranged in the shut-off device A such that the supply line 40 is blocked. The threshold value for the CO2 concentration of the respiratory gas is 3% of the respiratory gas in all exemplary embodiments. In this exemplary embodiment, the shut-off device A has a shut-off valve. However, the shut-off device A can also alternatively or additionally be connected to one or preferably both one-way valves V, which interrupt the gas supply to the gas delivery device 20 when the threshold value of the determined CO2 concentration of the respiratory gas is exceeded.If the measured CO2 concentration falls below the threshold, the shutdown device A is not activated and the user P can continue the hypoxia training.

[0057] The hypoxia device 1 also includes measuring devices that continuously monitor the health status of the user P during the hypoxia treatment and / or hypoxia training. In particular, a pulse oximeter is used to monitor the heart rate and blood oxygen content. The measuring devices are connected to a control unit that emits an alarm signal in the event of complications, e.g., too low oxygen content in the user's blood, so that the hypoxia treatment and / or hypoxia training is immediately discontinued.

[0058] In a further embodiment, the hypoxia device has an inlet and / or outlet valve. Using the inlet and / or outlet valve, it is possible to discharge or remove CO2 from the breathing circuit. Furthermore, the inlet and / or outlet valve allows air and / or oxygen to be introduced into the breathing circuit.

[0059] In an optional development of the previous embodiment, the CO2 sensor is coupled to a two-point controller with which the inlet or outlet valve can be controlled. If a first threshold is reached, the inlet or outlet valve can be opened to introduce air and / or oxygen or to discharge CO2. When the second threshold is reached, the inlet or outlet valve can be closed again. The first threshold for the CO2 content is at a higher CO2 concentration than the second threshold. Optionally, a third threshold can be provided, upon reaching which the shutdown device can be activated. The third threshold for the CO2 concentration is above the first and second thresholds. In a further embodiment, the hypoxia device has a CO2 absorber by which the CO2 from the exhaled air can be absorbed.In this embodiment, the CO2 sensor is arranged adjacent to the CO2 absorber to monitor its function. If the CO2 sensor detects a limited function of the CO2 absorber, the shutdown device can be activated. In an optional embodiment of the invention, the function of the CO2 absorber can be monitored by two CO2 sensors. The first CO2 sensor is arranged upstream of the CO2 absorber, and the second CO2 sensor is arranged downstream of the CO2 absorber. During monitoring, the measured values ​​determined by the CO2 sensors are compared.
